if you write such a script you will be able to create a set of .fschar
substitutions for base PS fonts from pseudo-afm files of ogokify project.
The files contain composition information in the form
CC Acircumflex 2 ; PCC A 0 0 ; PCC circumflex 0 130 ;
The files can  be found as *-c.afm in oginkify subdir of a2ps program.

Some more compositions (patches to the above):

If you are looking for rules to make substitution in any font (.fchar) -
you may look at
